Specific embodiment
To keep the purposes, technical schemes and advantages of the invention implemented clearer, below in conjunction in the embodiment of the present invention
Attached drawing, technical solution in the embodiment of the present invention is further described in more detail.In the accompanying drawings, identical from beginning to end or class
As label indicate same or similar element or element with the same or similar functions.Described embodiment is the present invention
A part of the embodiment, instead of all the embodiments.The embodiments described below with reference to the accompanying drawings are exemplary, it is intended to use
It is of the invention in explaining, and be not considered as limiting the invention.Based on the embodiments of the present invention, ordinary skill people
Member's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.Under
Face is described in detail the embodiment of the present invention in conjunction with attached drawing.
As shown in Figure 1, a kind of milling wheel device for ditching, including milling wheel body 1, cutter 3, tool fitting 2；Cutter 3
It is mounted in tool fitting 2, tool fitting 2 is orderly to be arranged on milling wheel body 1；Wherein, the arrangement side of tool fitting 2
Formula be by the outside of milling wheel body 1 to middle part helically line form；The cutter of multiple helical wire forms of the left and right sides constitutes milling wheel dress
The cutting part set.
It should be noted that cutter 3 is detachably arranged in tool fitting 2.
The preferred embodiment among the above about dismounting mode is given below:
The dismounting of cutter is common dismounting mode, is to be fixed using the Spring Card on cutter 3, is mainly herein
Want to illustrate that cutter is vulnerable part, be prone to wear in work, and tool fitting 2 is welded on milling wheel body 1, is not have to replacement
, cutter is to protect tool apron and design.
As shown in figure 3, two neighboring cutter point in the distance of milling wheel body axial direction is a, value a=h/ on same helix
2/n；In above-mentioned publicity, h is to excavate groove width, and n is the tool fitting quantity on single helix, and the parasang of a is fixed
Justice is mm.
With continued reference to shown in Fig. 3, α is cutter angle of rotation, arrangement, left knife and right knife edge on the outside of rotation angular divergence milling wheel
Milling wheel center line is symmetrical, wherein from outside to internal cutter angle of rotation from 50 ° to 0 ° in reduced by height.
As shown in Fig. 2, the cutting angle δ of each cutter is consistent, wherein 48 ° -55 ° of cutting angle δ range, foundation cut medium
